A very long time ago, sometime during the first geologic age, I worked at a facility on Queen Street in Toronto. On the street side of the building, we had two Flame suites (very high-end (for the time) realtime editing and effects, used for composing television commercials). Each one had a Sony Trinitron TV of about this size as the client preview monitor. They were amazing, but every time a streetcar passed outside, they would get involuntarily degaussed!
